Extended Data Fig. 3: Spatial distribution of thalamus- and medulla-projecting PT neurons.
From: Distinct descending motor cortex pathways and their roles in movement
a, The nuclei of PT neurons were retrogradely labelled from the thalamus (green cells) and medulla (magenta cells) using rAAV2-retro. Thalamus-projecting PT neurons are in upper L5b throughout motor cortex, whereas medulla-projecting PT neurons are in deep L5b. Schematics to the left of each image set are annotated coronal sections (Allen Mouse Brain Atlas54). b, rAAV2-retro injection sites in the thalamus (left) and medulla (right). Three biological replicates of this experiment yielded similar results.
